Render Solid Gridline while converting Excel to PDF with C++

For compatibility with older versions, Aspose.Cells renders gridlines as dotted lines by default while converting Excel to PDF. However, modern Excel renders gridlines as solid lines nowadays.

With the option PdfSaveOptions.PaginatedSaveOptions(PaginatedSaveOptions_Impl* impl), Aspose.Cells can also render gridlines as solid lines.

#include <iostream>
#include "Aspose.Cells.h"

using namespace Aspose::Cells;
using namespace Aspose::Cells::Rendering;

int main()
{
    Aspose::Cells::Startup();

    // Create an empty Workbook
    Workbook wb;

    // Prepare data
    wb.GetWorksheets().Get(0).GetCells().Get(u"D9").PutValue(u"gridline");

    // Enable to print gridline
    wb.GetWorksheets().Get(0).GetPageSetup().SetPrintGridlines(true);

    // Set to render gridline as solid line
    PdfSaveOptions pdfSaveOptions;
    pdfSaveOptions.SetGridlineType(GridlineType::Hair);

    // Save the pdf file with PdfSaveOptions
    wb.Save(u"..\\Data\\02_OutputDirectory\\test_Cpp.pdf", pdfSaveOptions);

    std::cout << "PDF file saved successfully with gridlines!" << std::endl;

    Aspose::Cells::Cleanup();
}
